PHP version and Zend API Number

Hi, Is there a way to get the version of the PHP binary that loaded an extension from within the extension? I don't mean the PHP version the extension was compiled with (PHP_VERSION), I mean the version of the PHP binary itself? Can I call the phpversion function from within an extension? Similarly is there a way to get the zend API version of the PHP binary (not the version the extension was compiled with)? Mike

mike@honeybadger:~/cvs/php-5.2$ grep -E 'version.*\);' Zend/*.h Zend/zend_API.h:ZEND_API char *zend_get_module_version(char *module_name); Zend/zend_extensions.h:void zend_append_version_info(zend_extension *extension); Zend/zend.h:ZEND_API char *get_zend_version(void); You could query ext/standard for the PHP version, everything else should be self explanatory.

Yes, that does give me the PHP version. Thanks. The get_zend_version function returns a string like 'Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies\n'. It would be nice to be able to get the ZEND_MODULE_API_NO (e.g. 20060613) the standard module was compiled under. I'm still confused about how many versions of extensions I need to provide with my product. Currently I just compile it against late versions of 4, 5.0, 5.1 and 5.2 and hope for the best. But looking at ZEND_MODULE_API_NO changes in webcvs shows it changes more frequently than that. But so far I haven't ran into major problems with ZEND_MODULE_API_NO so maybe I'm just being paranoid. From looking at zend.c it looks like it will print diagnostic info if some tries to load an incompatible extension. Mike

basic_function_module.zend_api might be what you're looking for.

It looks like that: mike@honeybadger:~$ php -n -dextension_dir=/usr/local/lib/php/extensions/no-debug-non-zts-20050922/ -dextension=ffi.so -v PHP Warning: PHP Startup: ffi: Unable to initialize module Module compiled with module API=20050922, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=1 These options need to match
